Itis thepri-ncipal object of thepresent invention to provide sheet'piling which are 7 -;preerably ;made of cementitious material and which are so 1 constructed .as to be readily driven and combined to form suitable piling structures, .such as cofierd ams and: the likeythelelements ofthe present inven- 2 tion being; so designed as'to make it possible (to readily matchupthe various piles and rto create watertightjoints.therebetween. of the tongues is a semicircular packing The present invention contemplates the 1gro0ve16, In some instances this groove use of a -p1ur ality of startingpiles, having ceXi endsthe entirelength of the tongue while wings, theaedgesiof wlliQh are =formed with in other cases it is discontinued in' manlongitudinal, interlocking joint members ner and for apurpose which willbe hereinadapted to cooperate with. complementary after set ,forth. -members eftsheet piling and, .whendriven The arcuatetongues are'adapted to mesh with arcuate grooves l4 which may be formed along-the wingsof the starting piling or along thewed'gesof thesheetpiling. These grooved menibers are of less depth than the corresponding tongues, thereby causing a slight space 17 to ;occur between adjacent shouldered 5 oi? the abutting members. The sheet piling issubstantially rectangular in ed an as sortrnent bf tongues and -groov .es ,upon the various elements, as, for .examplefin Fig. 1 three of the wings are providedwith.tongues'13 and onewing with a groove 14:. Variations of this arrangement might bemade without departingfrom the spirit of the invention. i i

During the driving operation it is also desirable to place a swab 20 within the recessed packing groove 16. as shown in Fig. 1. This will prevent pieces of cement and other bodies from falling into the packing grooves and clogging the same so that packing material cannot be forced therealong.

In some instances it is not necessary to pack the joint between the piling members for their full length as the lower ends of the members will be driven below the water line. For that reason a construction, indicated in Figs. 3 and 4, is provided. This consists in a filled-in portion 21, at the bottom of the packing groove 16 on the tongue member of a piling and a complementary filled-in portion 22 at the bottom of the packing groove of the groove member of the piling. These members have complementary arcuate faces forming 'continuations of the surfaces of the tongue and grooves along the edges of the piling, thus making it possible for the piling to rotate along their joints as provided by the slight spacing between the shoulders 15 without cracking or otherwise damaging the edges of the abutting piling. It will be understood that the filled-in portions 21 and 22 may extend for any desired length and as it is intended to precase these piles, the lengths will necessarily be determined before the piles are driven.

In the form of the invention shown at the left-hand'side of Fig. 3, a swab member 23 is secured to a bracket 2 L embedded within the edge of a pile. This swab is carried down as the pile is driven and will clear the packing joint grooves, at the same time filling thesame at the lower end.

In some cases it may be desirable to form a piling structure on the arc of a circle, in

which instance thesheet pile staves 25 are provided. As shown in Fig. 2, these members are each formed with'atongue and groove along their opposite vertical edges, and it is to be understood that other arrangements could be made, the same as in- 1 where certain of the piling are formed;

one with longitudinal tongues and grooves along their opposite edges; another with grooves along both edges; and anotherwith tongues along both edges. Due to this arrangement itis possible to make any sort of joint required and to insure that the sheet piling will match as they are driven along and between the various starting piling.

In the operation of the present invention, it is first intended to drive the starting piling, after which sheet piling may be'driven against the wings thereof. During the driving operation the swab 20 is positioned with- If desired, the various piling elements may be fastened together by irons 27. It will thus be seen that by the use of piling of the v construction here disclosed, it is possible to readily form and drive a desired length of piling and to insure that water-tight joints may be produced therebetween. Y

VVhile I have shown the preferred form of my invention as now known to me, it will be understood that various changes may be nade in the combination, construction and arrangement of parts by those skilled in the art without departing from the spirit of the invention as claimed.
